'Be t known that I, J OHN A. J ossnLYN", ,a

citizen of the United States residing. at

Natick, in the county of Middlesex and State of -Massachusetts, have invented new and useful Improvements in Heel-Building Ma-= chines, of which the following is a specification. i

This invention relates to a machinefof build ng and forming the heels of boots and shoes,

"The heels to be built and formed on the machine of this invention varefirst built up by hand from a series of lifts which are joined together by paste.

' condition is placed in a form, which form is The heel while in this expansible laterally thereof, and theheel is then submitted to lateral compression in the tom lift thereof, whereby the same is molded in the form and the difierent lifts aresecurely and closely pressedtogether. Subsequently to the forming operation the heel is shaved by a suitable knife'and then gouged on the bottom lift thereof. Finally the heel "is ejected from th machine, all of these different operations being performed automatically, while the carrier for the heel, upon which the form-is located, returns to have another heel built in the form located on said carrier, after said operations are completed.

The invention consistsin the combination and arrangement of parts set forth in the fol lowinp; specification and particularly pointed out ill/tile claims thereof.) '4 p I Referringto the drawings; F gjire 1 plan view of my improved heel chine, a portion thereofheingb i 1 to save space in thedrawintgsQ i j elevation of the same. 3 elevation taken on line e' u I is a detail section taken on line o.

elevation taken on line 7 1s a'perspective view of Fig. 6 is a sectional .6.6 of Fig. 1. Fig. the completed heel.

In the drawings, 10 is the frame of the me chine provided with ways llextending longituklinally. thereof and adapted to receive and 4 guide a carrier slide 12 upon which is located an expansible form 13 adapted to receive the ward the rig ht Lbears t t-t with the as viewed from the front of the machine. Fig. 5 is a sectional elevation broken away to 1 save space taken on line 55--'5- 2-5, Fig. 1.

ates is d ivenjby a p alle fastened theretoby ineans laterallyuponl the slide 12 and is-g'iiided'by screws 17 whichproject through slots'l'8 in the movable part. 16 and extend into "the slide 12. Springs 18 inserted inholes in the parts 14 and 16 tend to move the part-16 to- (Fig; l) or to expand the forni. The operator places the heel. a recess 19, about 'onefhalf of which is formed in the move able part 16'. and the other half in the fixed part ljei. ,of the e'xpansible form. Themovable part 16 ismoved toward the. ifixedpart 14 5 against the action-of the springs 18by means of a lever 20 which is pivoted at 21th a bracket 1 22last to the slide 12. Said lever extends forwardly fromits pivoted end and itsfree end 1s wedge-sh-aoed in cross section (see Fig;-

l) andbearsagainst the inclined outer edge of the movable part '16.

The outer-edge ofthe lever 20 bears against. guide. pins 23 and it will, be evident that when the lever .20 isforced downwardly, as

hereinafter described, the front end thereof, WhlCll const tutes a wedge, will force themovablepart-'- 16 of the form toward the left, thus contracting said form and submitting the heel contained therein to lateralcompression. The downward movement of the. lever 20, hereinbei'bre. referred to, is accomplished by-ineans of slide which ainst'tlie upper edge is 'uppenend bearsr ches fastenedto a sh ait' g transversely of the machine nal'e-d to rotate in hearingsfi, 2? he frame 10.

which held aspring 32 and is moveddownwardly to' release the cluteh and allow it to connect the pulley 29 to theshaift 26 by a lever 33, 2 pivoted at 346:0 the frame of the vertical arm of said lever being in alinement with an arm 35 iast to a collar 36 which,

the machine, 1

in turn, is fastened to a shaft 37. ,The

shaft 37 is .journaled to rotate-in suitable Cir formed in the lower end of a slide 75 which to the pulley 29. The

lmarings upon the frame of the machine and has a worm gear 38 fast thereto and meshing into a worm 39 which is rigidly fastened to the clutch shaft 40. The clutch shaft ltl is journaled to rotate in bearings 41, 41 upon the frame of the machine and has two pulleys 42 and 43 looselv mounted thereon' The pulley 43 is rotated by a straight belt (t l extending therefrbm to a pulley 45 fast to the main driving shaft 46, which is journaled to rotate in bearings '47 upon the frame 10. The driving shaft is rotated by a pulley 48 fast thereto and has a worm 49 fast thereto which meshes into a worm gear 50 formed upon the end of a hub 51fast pulley 4.2 is conhosted by a cross-belt 52 to a pulley 53 fast to the shaft 46. An intermittent reciproeatery motion is imparted to the carrier slide 12 by an intermittent gear 54. which is fastened to the shaft 37 and has teeth extending partly therearound. Said. gear 54 meshes into a rack 55 which is fastened to the carrier slide 12, Fig. 3.

tloinpression is given to the heel in a direction at right angles to the tread thereof by a plunger 56 (Fig. 3) formed of a lower part 57 and an upper part 58 adapted to slide one within the other. A pin 59 fast to the part 57 projects through a slot 60 in the part 58, while a spring 61 located in' a' recess 62 within the part 58 bears at its upper 1. against the part 53 and at its lower end :he upper end of the part 57, thus lg to keep said )arts in the position illustrated in Fig. 3. he upper end of the part 58 is connected by a connection 63 to a crank 6t upon the shaft 26. The lower end of the connection 63 has a ball 63 adjustably secured thereto which fits in a socket 58 in the upper end of the part 58, so that-the plunger 56 is connected by said ball-joint connection or by a universal joint counec tion to the crank 64.

A presser roll 65 (Fig. 3) fo m-id. pa of yielding material, such as rubb e", .astened to a shaft 66 journaled to rotate in a bracket 67 which is adjust bly fastened by a screw 68 to a cross-head I; rigidly sedurc-cl to the frame of the machine. The roll placed in. proper position to bear against the bottom lift of the heel as the 5 me is fed t rough the machine, as. he... ""ter do ihed, and adjacent to said. r if is a sta- '"y knife 70 which adapted to shave )ttom lift of the heel 5 Said stationary four.

. v .ened to cross-beam 7-1 which in turn, is fastened o the frame of the machine.

A rotarycutter 72 for gouging the bottom lift of the heel after it has been shaved by the stationary knife is fastened to a. shaft 73 which is journaled to rotate in a bearing 74 is adapted to slide vertically in the frame of see the the machine and is forced downwardly by a spring 76 which encircles a stem 77 extending upwardly from the slide and through a plate 78 fast to the frame of the machine.

A lever 79 (Fig. 2) is pivoted at 80 to the frame of the machine and is connected by a screw 81 to the slide 75. The free end of the lever 79 has a roll 82 journaled thereon and in alinement with a cam block 83 fast to the carrier slide 12, so that when said carrier slide is moved backwardly, as hereinafter described, at a certain time in the rotation of the machine, the cam 83 encounters the rol .82, lifts the lever 7 9 and thus moves the. slide 7 5, together with the rotarycutter 72, upwardlyso that the gou e in the bottom lift of the heel will graduallydecrease in depth from the breast'of saidhe'el toward the rear portion thereof. 4

The heel is ejected from the form by an ejector 84 which is adapted to slide vertically in the carrier slide 12 and has journaled thereon 'at its lower end a friction roll 85,

said slide and .into a convenient receptacle therefor located at the rear of the machine.

it is necessary that the slide which carries the heel which is to be compressed, shaved, gouged and ejected from the machine shall first move backwardly from the o erator to, the mechanism which compresses t e heel at. right angles to the tread thereof and then stop while said compression is takin place. After the compression has taken %ace the slide again moves backwardly unti the heel passes the shaving and gouging cutters to the extreme rear portion of the machine and until the heel is ejected from the form. Then the carrier slide moves forward again to its extreme forward position and stops so that the operator can place another heel in the form. To encmnpass these difierent motions a reversing clutch mechanism is pro vided which I will now proceed to describe.

Referring to Fig. 2 it will be seen that when the parts are in the position illustrated in said ii gors -that is, with the carrier slide 12 forward and the machine stationary in readi ness for the operator to place a heel in the expansible form, both of the clutches 90 and 91 are out of engagement with their respective pulleys 42 and 43. It will be understood that the clutches 90 and 91 are slidable longi-. tudinally of the shaft 40 and are splined- The le'fthand end 10. slide 94 toward stop lever 103" pivoted at. 104 to the frame of the machine and having its forward end coninected to a spring 105 while-its rearward end .106 rejects downwardly behind aslidefiIOT-T ell is arranged :to slide-upon 'the'frame of f the-inachin'e-and is guided byserew's 1'08} 108 which project through slots-10% 109 in said 20. slide.

earsagainst I pressing the clutch slide3l upwardly, engaging the clutch '30 to release the same from the 29, so that said clutch pulley is then free to rotate Withoutrotating the shaft 26 and said shaft 26 becomes stationary. .The slide 241 will alsomove upwardly into its uppermost position, heingcthus moved by the spring 28, as illustrated in Fig. 5. The lever 20, however, being wedged downwardly as hereinhe fore described between the the lured portion -14 oft heform. As soon as 85 e described l rocks said lever so' that thehorizontal arm being understood that theclutch pulley 29 is in liiled outer edge of the movable part 16 1-- 63 until the roe retreated to its uppermost posame; whereupon the spring 32 inoves'the clutch pulley l 60 said rack stationary, together with the gear guide-pins 23 and 50 inittent gear 54 in the directionof the arrow b (Fig. 2). Therotation ofthe intermittent gear 54in thedirectionof the arrow 1) moves the rack 55 and carrier slide 12, together with the expa'nsilzle form 13 and lever'-20, toward 55 the right or toward the hack of the machine until the heel is brought into-alinement with and underneath the plunger 56.: At this time the toothed portion of the gear 54 passes out of mesh with the rack 55, thus-leaving the movable part of. the expansihle form, will remain in this position-and'the lateral. compression of the heel will'continueuntil after the heel has passed the stationary knife 70 g and the rotary cutter or gouging cutterand just refers the heel isejected from the form, 121) whereupon a laterally projecting pin 1-18 will engage the inclined edge 119, Fig. 3, of a block fast to-the frame of the machine,- when, upon the continued movement or" the carrier slide, towhi'ch said lever is pivoted, 125 the lever 20 will he forced upwardly, thus releasing the movable portion of the expans'ihle form. Said movable portion is then forced away from the fixed portion by the springs .18', 18. After the plunger has bee and the parts connected thereto. .During this backward movement of the rack and liefore the plunger compresses the heel the arm 35 upon the collar 36 engages the lower 65 end of the vertical arm of the lever 33 and n raised L30.

I lsufliciently torelease the vertical compress10n upon the heel the gear 54 again meshes and as'the heel is subsequently carried by'the 10 carrier slide toward the rear of the machine, said heel is gouged at 121 by the rotary cutter "72. The gouge 121 is for the purpose of enabling the heelto fit the rounded portion of the shank of the shoe sole, and thus renders thecompletedheel independent of the com-- pressing machine which is ordinarily used engage the right angled or this purpose.- i In order tocause the gouge to decrease in depth from the breast toward the rear of the heel, as shown in Fig. 7 ,therotary cutter 72 is moved upwardly by reason of the cam block 83 -coming into contact with the roll .82, which moves the lever 79 upwardly and thus lifts the rotary cutter gradually until it clears the heel. After having been thus compressed, .shaved and gouged the form releases the heel from side pressure, as hereinbefore described, and the heel is ejected by the ejector 84 which rides upwardly on the cam block 86 and pushes the heel out of the form and up between the two side arms of the U-shaped spring ejector 87. The parts are now in position to have the slide reverse its movement and move forward, whereupon the cross-bar of the e ector fin-- ger 87 will engage the heel and push the same off of the slide, said heel sliding downwa'rdly over the curved inclined plate 88 and into a suitable receptacle, whie the slide passes forward to the front of the machine and stopsto have a new heel placed therein by the operator. In order to accomplish this reversing movement the pin 112, which is, fastened to the collar 36, is so placed relatively to the other parts as to, at this time, late 111 and move the same toward the rig it (Fig. 2), and the slide 94 will also be moved to the right, moving the downwardly projecting arm 92 and the clutch sleeve 90 toward the right and out of engagement with the clutch pulley 42. The slide 98 is then moved upwardly by the treadle 99 and by the spring 122 which is fastened to said treadle. The left hand end of the slide 94 thus projects into the notch 97 in the upper end of said slide 98 and will remain in this position until said slide is'depresser'l by the operator, as hereinhefore descrilved, upon the commence.-

ment of a new cycle of operations of the mechanism hereinbefore described.

When the slide 94 is moved toward the right, as hereinhefore described, theextended arm 102 fast thereto will engage at its right hand end (Fig. 2) the'left hand end of s ring-1 10, thus moving the arm 115 and the c utch sleeve 91', which it engages toward the right until said clutch sleeve engages the pulley 43, which, it will be remembered, rotates in the opposite direction to that in which the pulley 42 rotates. Thus theshaft 40 will be rotated by the pulley 43 in the direction opposite to the arrow a and the intermittent gear 54' will be rotated in the direction opposite to the arrow 6, thus moving the slide 12 toward the front of the machine until it is stopped by the pin 114 engaging the angle plate 113 and moving the slide 107 toward the left (Fig; 2), thus moving the clutch sleeve 91, through the downwardly projecting arm 115 toward the left and disengaging said clutch sleeve from the pulley 43, whereupon the shaft 10 becomes stationary. and the several arts are then in the position illustrated in ig. 2. 1

It has been found to be very advantaeous in amachine of the character hereinefore described to use a flexible material, such as rubber, for the presser roll 65, for the reason that the same bears against the leather of the heel and is flattened at that ortion thereof which bears against said heel, so that instead of bearing along a line extending longitudinally thereof, as would be the case in a roll formed ofhrass hard material, said roll, when formed of 1" will bear along the flattened portion of periphery against the leather of the heel and such flattened portion will hold the heel firmly in position in theform and close to the edge of'the stationary knife 70, so that the shaving will be done without any vibra-,

tion or chattering of the heel in the form.

- As hereinbefore set forth the heel is com pressed laterally during the first part of the re'ciprocatory motion of the carrier slide and. is heldcompressed While the slide subse quently in a stationary position, and while said heel is bein subjected to corn on verticall or upon the bottom lift thereof, said hee is also held under lateral compression during the further forward. movement ofthe slide and while the heel is beingshaved and gouged. There are severaladvantages in thus sub ecting the heel to lateral com-- pression in the manner and during the time 1 set forth.

First, more satisfactory results are obtained by compressing the heel laterally prior to the vertical compression thereof or the compression at right angles to the bottom lift of the heel.

Second, holding the heel under lateral compression intheform during the shaving and gouging operations makes much more satisfactory work, for the reason that heel is firmly held and'cannotjchatter a the time when the shaving and gouging. op erations are taki place; and I pression during the entire timetakenrby all of the other ,eration'sto whiohi 'it i'ssub-13 jected-eXcept. t e timetakenitofj'ectthe heel" from the machinegand it isf'well known to; ,those' skilled in the art that th i sub ected to lateral compression, and in'stru V asudden blow or to *avlongcontmuedpres sure. ,"120' Havingthusdescribed my t lw ti er ai b lmentalit ie's adapted to move said cutter to- 7 5 ward"-and aWayfr I saiddleel- 4, a heel building machmcarrier ,"rnechani in to impart .areciprocatory 111015011 to -sa'-" slide, a'form on said slide wool-parts, ne'movable relatively, to the adapted t'o'move said movable .part-toward-fthe' other part of saidform to I claim and desire by Letters Ratent-to se" ;.cure1s 1 1.
